ADJUSTABLE SIDE BEARING.

Specication of Letters Patent.

Patented Apr. 17, 1917.

Application filed April 17, 1916. Serial No. 1,592

Toall whom t may concern:

Be it known that I, JOHN J. HENNESSEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee4 and State of Wisconsin, have invented a certain new and useful Improvement in Adjustable Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in adjustable side bearing.

The object of the invention isto provide a rocker side bearing adapted for use on railway cars and so arranged that adjustment may be obtained in accordance with the spacing between the car holsters.

Another and more specific object of the invention is to provide a gravity rocker side bearing employing a horizontal reciprocatto plate andlhaving means to adjust the height of the topplate relatively to the base member of the side bearing..

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described or claimed.

In the drawing Vforming a part of this specification, Figure l'is an end elevation of portions of a body and truck bolster showing my improvements in connection therewith. Fig. 2 is a vertical sectional view of the improved side bearing and taken substantially on `the line 2-2 of Fig.l 1, the Section being upon an enlarged scale. Figs. 3 and 4@ are transverse, vertical sectional views of the sidebearingtaken 0n the lines 3 3 and 4-41respectively offFig.- 2.

Inrsai'd drawing, `10 denotes a body bolster which is pivotallyconnected'at thecenter to the truck bolster 11 in the usual manner, the body bolster being provided with a striking plate 12 which coperates .withmy proved side bearing designated generally by the reference A and which ismounted on the truck bolster.

The improved 'side' bearing A comprises broadly a base casting B, a top plate C, a bottom plate" D, a pair of rockers E-E and aspring F, together with various details of construction cooperating therewith, as hereinafter described.

The base casting B is provided with a flat bottom 13 adapted to be riveted to a bolster, said casting B having a pair ofupstanding side walls llt-'14, said walls 14 on their inner faces being provided with'a longitudinally extending series of tongues and grooves 15. rlhe bottom plate D is of substantially U-shape in cross section as ap pears from Fig. 3, .said member D having a lower wall 2.6 and side walls 17-17, the latter on theiil outer faces being provided with a series of tongues and grooves 18-18 which ccper ate with the tongues and grooves 15 on the base casting. The upper surface of the lower wall 16 is convex as indicated at 19 and forms bearings for the rockers, the peripheries of which are concaveas indicated at 20. Each of the rockers E, on its lower periphery is provided with a series of recesses 21, which coperate with a corresponding series of bosses 22 on the member D, to thereby retain the rockers in proper position. The bottom plate D is .provided at its center with a transversely extending limiting wall 23 having. bosses 24 on each side thereof at the center, the `rockers being limined in their movement by engagement with said wall, the rockersbeing provided with grooves 25 on both sides, seel Fig. 2, which iit the bossesA 24: At their upper ends, eich of the rockers E is rovided with a cylindrical knob 26 which fits a correspondir gly shaped bearing 27 formed on the under side'of the top plate C. To retain the top j )late G in normal position and return it to such position after each actua-l tion of the sa me, the spring F is attached thereto as indpcated at 28, the opposite end of said spring being attached to an eye bolt 29, which pass es through a suitable perfora- "tion in the wal 23, the lower end of the bolt being providel with a nut 30 seated in a countersink 3L in the underY side of the lower plate D. On each sideof the plate C,

the side walls hereof are prvided with out wardly extending lugs 32 and 33 between which is seated the upper flange 34 of a retaining plate 35, the retaining plate 35 extending dowrwardly and having an inturned lower ilange 36 which extends under an outwardly extendedflange 37 along the top of the corresponding side wall ofthe bottom plate I). The retaining plates 35 are detachably hed in position by any suitable means such as the cotters 38.

As clearly appears from Figs. 1 and 2, the base casting B is provided at each end thereof withvan outwardly extended pair of perorated ears USL-39, through which passes the bolsters approach yeach other and have relative radial l"movement, the vamount of movement of the plate C being 4limited by the engagement .of ,one of the rockers E with the li-mitin Wall .Uponfre easewo'fv the pressure on the top plate C, 'the latter will be returned to normal position .by means of the spring F. Accidental lifting :or removal of lthe-top plate C :from the bottom `plated) is prevented by the :retaining plates which, lor course, operate in .conjunction with the spring F. The parts as shown in the drawing represent the topsufrface 'of the plate C in'its lowermost position, but in .order to increase the height of, the. 1 upper surface. Y of :said vplate -G relatively `to the ibase; .casting B, 'the bolts -40 are WithdraWmLater. which the top pla-te C, rockers Efandbbttom plate-D lare removed as 'va-unit by sliding the same lengthwise lof the basecasting B. The members C, D' and may then be replaced @in ,a higher position byfengaging the'tongues land grooves of the member Dat higher point-s inthe tongues and. grooves of the 'side walls 14 of the base casting. The partsare then locked in positien .by :replacing the'bolts'40L lAs willbe understoodirom the foregoing, various adjnstments may'gbe made depending upon the relativepositions in 'which the,bottom plate D and base casting-B are assembledv and a changemay beviery easily made without disturbing the rockers or the mounting thereof between the members B and C.

Although I have herein shown and dev scribedwhat now consider the preferred embodiment ef'm-y invention, the' same is nverelyillustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:

i 1.- InY arockerside bearing, the combination 'with a base member, of a top plate, rockers located between said top plate andbase member, and means for adjusting said rirerents each, 'by addressing the Washington, D. Q.

top plate and rockers as a unit and without disturbing the relation therebetween, vertically relatively to said base member.

2. In a side bearing, the combination with 'a base casting, of a horizontally reciprocat-' ing top plate, a plurality of members interposed between said top plate and base casting, and means for adjusting said top plate and members vertically, as a unit and without disturbing the relation therebetween, relatively to said base casting.

3. In a side bearing, the. combination with a base casting, of a top plate, a bottom plate, rochers interposed between -said top and bottom plates, and means permitting adjustment of said bottom plate, top plate, and rockers as a unit and Without disturbing the relation therebetween, vertically relatively to the base casting.

4. In a side bearing, the combination with a base cast-ing having npstanding, spaced side Walls, of a bottom plate slidiably mounted betweenthe side walls of the base casting, a reciprocating top plate, rockers interposed between said top and bottom plates, and detachable mean-s at the ends of said base casting for retaining said bottom plates and the parts mounted thereon, in roperative position.

5. In a side bearing, the combination with a `base castin and a bottom plate relatively vertically adjustable, of a reciprocating top plate, rockers interposed between said top and bottom plates, and a spring connected to said top and bottom `plates adapted toreturn the top plate to normal position after each vactuation thereof.

6. Ina side bearing, the combination with a base casting havin upstanding, spaced side walls provided with longitudinally-extending tongues an-d grooves on their inner faces, of a bottom plate, the side walls of which are provided with longitudinally -eX- tending tongues and grooves coperable with those of said .base casting, transversely extending bolts mounted in said base casting at the ends .thereof and adapted to prevent removal of said bottom plate from the'base Commissioner of Patents,
